A word on drilling framing members

In the past few months, our inspectors have noticed a number of situations where over-large holes have been drilled in framing members, or, alternately, holes have been drilled too close to the edge of a framing member.

We remind contractors of the relevant code on drilling holes through load-bearing elements: Holes Drilled in Framing Members
Holes drilled in roof, floor or ceiling framing members shall be not larger than one-quarter the depth of the member and shall be located not less than 50 mm from the edges, unless the depth of the member is increased by the size of the hole.

The hole for this pipe exceeds the allowed diameter for a 5.5" stud. It is also too close to the edge.

Our inspectors have also observed holes for plumbing – usually for draining toilets or showers - drilled through the top members of open-web joists in the floor system below. This requires the contractor to contact the joist manufacturer for an engineer-approved repair, at the contractor’s expense.

If you have questions, give us a call. Our building inspection department serves rural Charlotte County, southern York County, and the municipalities of St. George, Saint Andrews, Harvey and McAdam.
